This is as close to "walking the beach" that I found in the Keys. Wooden walkway along a beach area. There is a small parking lot at each end of the walkway. I don't recall that there were stairs, so this would be accessible for anyone in a wheelchair. Leisurely walk took us about 10-15 minutes each way. Plenty of picnic tables to stop and eat or soak up the ocean smell & view. Didn't really see much beach that you'd want to lay a towel down on.
